About me

At KTH, I work as a permanent researcher with a focus on railway energy and railway sustainability. I have been working and researching in the railway field since 2008. I have joined the system development and commissioning trials of the high-speed railways (with a top speed of 420 km/h). To make rail transport more reliable, more affordable and more attractive, in the past 15 years I have participated in more than 20 railway-related research projects and published 50 publications (conference and journal articles) about research on rail transport systems. I have been acting as PI in 4 research projects (financed by EU, Swedish governmental agencies and railway industry) and Co-PI in 5 research projects. At the same time, I also contribute to the railway education at KTH. I am a teacher in 9 courses on transport systems. I have been the main supervisor of 5 bachelor's theses and 10 master's theses. I also act as co-supervisor of several doctoral students. I have also looked into the theory of pedagogy in higher education and finished5 pedagogical courses at KTH. Based on the pedagogical theory and my experience in teaching and supervision, I have written a report that is included in the course material of a pedagogical course(LH219V) at KTH.
